Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a triple-layered door. Background Technology

[0002] A triple-layered door is a special type of automatic door, consisting of three doors that operate in tandem via a special track and pulley system. In daily use, the three doors can overlap, typically consisting of two sliding and one fixed door. The design of the triple-layered door allows for a clear opening width that is 1.3 times that of a regular sliding door for the same doorway width. However, in some locations with limited space, even with a clear opening width 1.3 times that of a regular sliding door, it may still not meet the requirements for clear passage, especially in emergency situations requiring evacuation. Furthermore, the activation sensors are inconvenient to quickly disassemble and reassemble, hindering future maintenance and repair. Therefore, we have proposed a triple-layered door to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings by proposing a triple-layered door.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A triple-layer door includes a cover panel, a sliding swing door one, a sliding swing door two, a swing door, and a start sensor. The start sensor is located on the front side of the cover panel. Two swing-sliding motor units are installed inside the cover panel. The sliding swing door one and the sliding swing door two are slidably installed inside the cover panel. The sliding swing door one and the sliding swing door two are respectively engaged with the corresponding swing-sliding motor units. The swing door is rotatably installed on the cover panel. A mounting sleeve is fixedly connected to the front side of the cover panel. A connecting plate is fixedly connected to the rear side of the start sensor. A convenient disassembly and assembly mechanism is provided between the connecting plate and the mounting sleeve.

[0006] As a preferred embodiment of this utility model, the convenient disassembly and assembly mechanism includes two rotating shafts rotatably connected to the inner walls of the front and rear sides of the connecting plate. Toothed pulleys are fixedly sleeved on the outer side of the rotating shafts, and the same toothed belt is drivenly connected to the two toothed pulleys.

[0007] As a preferred embodiment of this utility model, the upper and lower inner walls of the mounting sleeve are provided with slots, the outer side of the rotating shaft is fixedly fitted with a cam, the front side of the cam is rotatably connected to two push-pull rods, the ends of the two push-pull rods that are far apart from each other are rotatably connected to a lifting plate, the outer side of the lifting plate is fixedly connected to a locking rod and a return spring, the ends of the four return springs that are far apart from each other are respectively fixedly connected to the upper and lower inner walls of the mounting sleeve, and the four locking rods are respectively movably engaged in the corresponding slots.

[0008] As a preferred embodiment of this utility model, the upper and lower surfaces of the connecting plate each have two through holes, and the four locking rods are respectively slidably sleeved in the corresponding through holes.

[0009] As a preferred embodiment of this invention, the four reset springs are respectively sleeved on the outer side of the corresponding locking rod.

[0010] As a preferred embodiment of this utility model, the inner side of the lifting plate is fixedly connected to an ear plate, and the four push-pull rods are respectively rotatably connected to the front side of the corresponding ear plate.

[0011] In a preferred embodiment of this utility model, a handwheel is fixedly connected to the front end of the rotating shaft, an external gear is fixedly sleeved on the outer side of the rotating shaft, a fixed sleeve is fixedly sleeved on the front side of the connecting plate, a rectangular groove is formed on the top inner wall of the fixed sleeve, a lifting screw is threadedly connected to the top of the fixed sleeve, and an arc-shaped internal gear ring is rotatably connected to the lower end of the lifting screw, the arc-shaped internal gear ring meshing with the external gear.

[0012] In a preferred embodiment of this invention, the arc-shaped internal toothed ring is slidably fitted inside the rectangular groove, a knob is fixedly connected to the top of the lifting screw, and the lower end of the lifting screw is rotatably connected to the top of the arc-shaped internal toothed ring via a bearing.

[0013] In this utility model, a triple-layered door consists of a sliding hinged door and a sliding hinged door. In normal operation, the sliding door is driven by a sliding mechanism. A sensor receives external signals, and when people approach, sliding hinged doors one and two can slide open. During daily use, the sensor detects the approach of people and automatically controls the opening and closing of sliding hinged doors one and two, enabling convenient passage. At this time, sliding hinged doors one and two will slide to a position overlapping with the hinged door to save space and maintain a clean passageway. In emergencies, such as fires or other scenarios requiring rapid evacuation, this emergency evacuation door design demonstrates its unique advantages. Sliding hinged doors one and two will slide to a position overlapping with the hinged door, and then sliding hinged doors one, two, and the hinged door can be manually opened, greatly expanding the passage space and facilitating the rapid evacuation of large numbers of people.

[0014] In this utility model, a triple-layered door features a rotating lifting screw. Guided and limited by a rectangular groove, the lifting screw causes the arc-shaped internal gear ring to move upward without engaging with the external gear, thus preventing the rotating shaft from locking. A handwheel rotates one shaft, which, through the transmission of two toothed pulleys and a toothed belt, drives the synchronous rotation of two shafts and cams. The rotation of the two cams causes four push-pull rods to move closer together. These four push-pull rods then cause four lifting plates and four locking rods to move closer together and disengage from their slots. The lifting screw is then rotated in the opposite direction, causing the arc-shaped internal gear ring to move downward and engage with the outside of the external gear, thereby fixing the locking rods in place. Without fixing the connecting plate to the outside of the slot, the connecting plate and the start sensor can be disassembled together for inspection and maintenance. After maintenance, the connecting plate is put into the mounting sleeve, and the lifting screw is tightened, causing the arc-shaped internal gear ring to move upward and engage with the external gear. At this time, under the elastic force of the return spring, the four locking rods move outward and are respectively locked in the corresponding slots, thus fixing the connecting plate and the start sensor. To ensure the installation is firm, the lifting screw is tightened lastly, causing the arc-shaped internal gear ring to move downward and firmly abut against the outside of the external gear, thus locking the shaft and locking rods, greatly improving the stability of the installation.

[0015] This utility model has a reasonable structural design. By changing the existing overlapping door, it enables each of the three door panels to be manually opened after they are overlapped, thereby greatly expanding the passage space, facilitating the rapid evacuation of a large number of people, and making it easy to install and remove the start sensor securely, which is beneficial for future disassembly, repair and maintenance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-7 A triple-layer door includes a cover plate 1, a sliding swing door 2, a sliding swing door 2, a swing door 5, and a start sensor 4. The start sensor 4 is located on the front side of the cover plate 1. Two swing and sliding units 6 are installed inside the cover plate 1. The sliding swing door 2 and the sliding swing door 2 are slidably installed inside the cover plate 1. The sliding swing door 2 and the sliding swing door 2 are respectively engaged with the corresponding swing and sliding units 6. The swing door 5 is rotatably installed on the cover plate 1. An installation sleeve 9 is fixedly connected to the front side of the cover plate 1. A connecting plate 8 is fixedly connected to the rear side of the start sensor 4. A convenient disassembly and assembly mechanism 7 is provided between the connecting plate 8 and the installation sleeve 9.

[0026] The above scheme employs a sliding hinged door system: Sliding hinged door 2 and sliding hinged door 3, in normal operation, are driven by the sliding mechanism 6. A sensor 4 receives external signals, and sliding hinged door 2 and sliding hinged door 3 can slide open when people approach. In daily use, the sensor 4 detects the approach of people and automatically controls the opening and closing of sliding hinged door 2 and sliding hinged door 3, enabling convenient passage. At this time, sliding hinged door 2 and sliding hinged door 3 will slide to a position overlapping with hinged door 5 to save space and maintain the cleanliness of the passageway. In emergencies, such as fires or other scenarios requiring rapid evacuation, this emergency evacuation door design demonstrates its unique advantages. Sliding hinged door 2 and sliding hinged door 3 will slide to a position overlapping with hinged door 5, and then sliding hinged door 2, sliding hinged door 3, and hinged door 5 can be manually opened (e.g., ...). Figure 2 As shown in the figure, this greatly expands the passage space, making it easier for large numbers of people to evacuate quickly.

[0027] Furthermore, refer to Figure 1 , Figures 4-7 The convenient disassembly and assembly mechanism 7 includes two rotating shafts 702 rotatably connected to the inner walls of the front and rear sides of the connecting plate 8. A toothed pulley 703 is fixedly sleeved on the outer side of the rotating shaft 702. The same toothed belt 704 is drivenly connected to the two toothed pulleys 703. The upper and lower inner walls of the mounting sleeve 9 are provided with slots 701. A cam 705 is fixedly sleeved on the outer side of the rotating shaft 702. Two push-pull rods 706 are rotatably connected to the front side of the cam 705. The ends of the two push-pull rods 706 that are far apart from each other are rotatably connected to a lifting plate 707. The outer side of the lifting plate 707 is fixedly connected with a locking rod 709 and a return spring 708. The ends of the four return springs 708 that are far apart from each other are respectively fixedly connected to the upper and lower inner walls of the mounting sleeve 9. The four locking rods 709 are respectively movably locked in the corresponding slots 701.

[0028] Using the above scheme: Rotating a shaft 702 drives the synchronous rotation of the two shafts 702 and cams 705 through the transmission of two toothed pulleys 703 and a toothed belt 704. The rotation of the two cams 705 causes the four push-pull rods 706 to move closer to each other. The four push-pull rods 706 drive the four lifting plates 707 and four locking rods 709 to move closer to each other and disengage from the locking slots 701, thus not fixing the connecting plate 8. At this time, the connecting plate 8 and the start sensor 4 can be disassembled together for inspection and maintenance. After maintenance, the connecting plate 8 is put into the mounting sleeve 9, and the shaft 702 and handwheel 710 are loosened, so that the arc-shaped internal gear ring 712 moves upward and abuts and meshes with the external gear 715. At this time, under the elastic force of the return spring 708, the four locking rods 709 move outward and respectively lock into the corresponding locking slots 701, thus fixing the connecting plate 8 and the start sensor 4.

[0029] Furthermore, two through holes are provided on the upper and lower surfaces of the connecting plate 8, and four locking rods 709 are slidably sleeved in the corresponding through holes. Four return springs 708 are respectively sleeved on the outside of the corresponding locking rods 709, which helps to guide the locking rods 709 and the return springs 708, making their movement more stable and smooth.

[0030] Furthermore, an ear plate is fixedly connected to the inner side of the lifting plate 707, and four push-pull rods 706 are rotatably connected to the front side of the corresponding ear plate, so that the four push-pull rods 706 can be rotatably connected to the inner side of the corresponding lifting plate 707.

[0031] Furthermore, refer to Figure 4 and Figure 6A handwheel 710 is fixedly connected to the front end of the rotating shaft 702. An external gear 715 is fixedly sleeved on the outer side of the rotating shaft 702. A fixed sleeve 711 is fixedly sleeved on the front side of the connecting plate 8. A rectangular groove 714 is opened on the inner wall of the top of the fixed sleeve 711. A lifting screw 713 is threadedly connected to the top of the fixed sleeve 711. An arc-shaped internal gear ring 712 is rotatably connected to the lower end of the lifting screw 713. The arc-shaped internal gear ring 712 meshes with the external gear 715. The arc-shaped internal gear ring 712 is slidably sleeved in the rectangular groove 714. A knob 716 is fixedly connected to the top of the lifting screw 713. The lower end of the lifting screw 713 is rotatably connected to the top of the arc-shaped internal gear ring 712 through a bearing.

[0032] By adopting the above solution, the rotating shaft can be locked by the abutting engagement of the arc-shaped internal gear ring 712 and the external gear 715, which in turn can lock the locking rod 709, thereby improving the firmness of the locking rod 709 in fixing the connecting plate 8.

[0033] In this invention, sliding hinged doors 2 and 3, in normal operation, are driven by the sliding mechanism 6. A sensor 4 receives external signals, and sliding hinged doors 2 and 3 can slide open when people approach. During normal use, the sensor 4 detects the approach of people and automatically controls the opening and closing of sliding hinged doors 2 and 3, enabling convenient passage. At this time, sliding hinged doors 2 and 3 will slide to a position overlapping with hinged door 5 to save space and maintain the cleanliness of the passageway. In emergencies, such as fires or other scenarios requiring rapid evacuation, this emergency evacuation door design demonstrates its unique advantages. Sliding hinged doors 2 and 3 will slide to a position overlapping with hinged door 5, and then sliding hinged doors 2, 3, and 5 can be manually opened (e.g., ...). Figure 2 As shown in the figure, this greatly expands the passage space, making it easier for large numbers of people to evacuate quickly.

[0034] When maintenance of the start sensor 4 is required, the lifting screw 713 is rotated by knob 716. Under the guide limit of the rectangular slot 714, the lifting screw 713 drives the arc-shaped internal gear ring 712 to move upward without engaging with the external gear 715, thus not locking the rotating shaft 702. By rotating one rotating shaft 702 through handwheel 710, the two rotating shafts 702 are driven to rotate synchronously with the cams 705 through the transmission of two toothed pulleys 703 and toothed belt 704. The rotation of the two cams 705 drives the four push-pull rods 706 to move closer to each other. The four push-pull rods 706 drive the four lifting plates 707 and four locking rods 709 to move closer to each other and disengage from the locking slots 701. Then, the lifting screw 713 is rotated in the opposite direction, causing the arc-shaped internal gear ring 712 to move downward and engage with the external gear 715. The outer side of the slot 701 can be used to fix the locking rod 709 to the outside of the slot 701, thus not fixing the connecting plate 8. At this time, the connecting plate 8 and the start sensor 4 can be disassembled together for inspection and maintenance. After maintenance, the connecting plate 8 is put into the mounting sleeve 9 and the lifting screw 713 is tightened, so that the arc-shaped internal gear ring 712 moves up and abuts against the external gear 715. At this time, under the elastic force of the return spring 708, the four locking rods 709 move outward and respectively lock into the corresponding slots 701, thus fixing the connecting plate 8 and the start sensor 4. In order to ensure the firmness of the installation, the lifting screw 713 is tightened, so that the arc-shaped internal gear ring 712 moves down and firmly abuts against the outside of the external gear 715, thus locking the rotating shaft 702 and the locking rod 709, greatly improving the stability of the installation.
